VILLIAM II. DIGKEY, OF JACKSON, MICHIGAN.

CENTRIFUGAL REEL.

SPECIFICATION forming part of Letters Patent No. 302,220, dated July 15,1884.

Application filed April 17, 1884. (No model.)

is a detached view, enlarged. Fig. 3 is a detached view, also enlarged,of the sleeve-bearing. Figs. 4 and 5 are detached views, enlarged,showing modifications. Fig. 6 is a plan or top view of one end of thereel-trunnion, the gear having been removed, and showing the groove clas being cut entirely through the trunnion.

Referring particularly to Figs. l, 2, and 3, A is the beater-shaft, itsends a a being ot' reduced diameter, forming shoulders, for a purv posewhich will be explained. B B are spiders, and b b are beaters mountedupon and carried spokes or arms and iiange ofthe reel-head at thedischarging end of the Inachine. The spokes C C project radially from ahollow trunnion or tubular support, D, which extends through the casing,and is mounted in a bearing, F', which parts may be of any usual orapproved construction. F is a chamber or offal-box having a circularopening in its inner wall,the opening being concentric to the tubularsupport D D. cis a circular flange formed upon the reel-head, and alsoconcentric to the tubular support D, so as to rit closely the opening inthe offalboX- The reel-head at the opposite end of the bolt consists ofan outer rim,-H, connected by means of curved arms la /L to a hollowtrunnion or tubular support, D, like that at the .discharging end of thereel.

As the construction of the tubular supports and the bearings at each endof the -reel are substantially alike, I will describe one of them only.

Referring particularly to Figs. 2 and 3, the bearing is constructedwithacentral spherical portion, E, having two projecting cylindricalportions, E E2, and is provided with a 1ongitudinal opening or seat toreceive the end C C are respectively the` of the beater-shaft. Thetubular support D is enlarged at its outer end and constructed with aconcave shoulder, substantially as indicated at d, to receive andsupport the opposing adjacent face of the sleeve-bearing. This bearingis provided at its greatestv diameter with a projecting lug, e, whichenters and is seated in a groove, d', in the inner face of the tubularsupport. In order to retain the sleevebcaring in proper position, andalso to preventlongitudinal movement of the beater-shaft, I eniploystops rigidly attached to the beater-shaftV at its ends which projectbeyond the sleevebearings. By preference the stop at the tail end ordischarging end consists of aspur-pin ion, G, which meshes with thespur-gear G', having attached thereto aspur-pinion, g, meshing with aspur-gear, g', which is rigidly afxed upon the tubular support D, sothat when the beater-shaft is rotated this train of gearing rotates thereel at a reduced speed. The stop at the opposite end or receiving endof the bolt may consist of a simple collar, I, keyed or otherwiserigidly attached tothe beater-shaft. f

.In Fig. 4 I have shown a construction in which the beater-shaft is ofuniform diameter from end to end, the parts being otherwise constructedsubstantially as indicated in Fig. 1, except that the stop, which inthis instance is a pinion, G, does not engage with the outer end ofthetubular support, but is in close cont-act only with the outer end ot'the cylindrical part EZ ofthe sleeve-bearing. In this figure thebeatershaft is shown as being of uniform diameter throughout. In Fig. 5the opening in the tubular support is of uniform diameter from end toend, and hence the stops on the shaft should be arranged to engage withnot only the outer ends ofthe sleeve-bearings, but

also with the outer ends of the tubular sup y port at both ends of thereel, in order to prevent longitudinal movement of either thebeater-shaft or the sleeve-bearings. In Figs. 4. and 5 the upper side ofthe tubular support is slotted, as at d, to receive the pin or lug c,which prevents the sleeve-bearing from rotating. f

In Fig. 6 I have shown the pin e as projecting entirely through the slotwhich is formed in the trunnion and extends to one end thereof, asindicated at d', while in Figs. Iand2 the pin does not project entirely.through the trun- IOO Among the advantages which are incident to thisinvention are the following: In consequence ofthe tubular support, thesleeve-bearing, and the beater-shaft being mounted upon or in a singlebearing or boxing at each end of the reel, there is much less liabilityof any disturbance in the alignment of these bearings than there wouldbe if the bearings for the ends ot' the shaft were separate from thebearings for the tubular supports of the reel, and this is true eventhough the shaft-bearing and the tubular-support bearing were both castin the same piece with the shaft-bearing` at some distance farther fromthe end of the machine than the tubular support and trunnion-bearing, asis the case in, for instance, the reel shown in Patent No. 266,781, W.B. Dell, October 8l, 1882, upon which this invention is intended as animprovement. By reference to that Dell patent it will be seen that thereare separate and independent supports for the beater-shaft and thetubular reel-supports at both ends of the machine, these supports beingat such distance apart as topermit the introduction of mechanism betweenthem, Whereas in my invention the boxing which supports the beater-shaftand the tubular reelsupport is one and the same, and is arranged'between the spur-pinion G and the collar I.

Another advantage is the facility With which long sleeve-bearings forthe beater-shaft may be employed, it being apparent that they may bemade to project to any desired length inside of the tubular supports D.aAgain, by reference to Fig. 5, it will be readily understood that thespur-pinion G and the stop at the other end ofthe machine serve not onlyto confine the sleeve-bearings in position relative to the beater-shaft,but also prevent longitudinal movement of both the bearings and theshaft relative to the tubular supports. In all the' constructions shownthe sleeve-bearings are placed loosely within the tubular supports, andare held in position against lateral play only by the stops, which areaffixed to the beater-shaft and engage with the outer ends of saidsleeve-bearings.

l. In a Hour-bolt, the combination of a reel. having a head providedwith a projecting tubular support, a beater-shaft within the tubularsupport, a sleeve -bearing mounted loosely in said tubular support, aboxing on the frame supporting both the sleeve-bearing` and the tubularsupport, and a stop attached to the beater-shaft to prevent it frommoving longitudinally in the sleeve-bearing, substantially as set forth.

2. In a flour-bolt, the combination of a reel having a head providedwith a projecting tubular support, a beatershaft within the tubularsupport, a sleeve-bearing surrounding the beater-shaft and having aglobe-shaped expanded portion, a boxing on the frame supporting both thesleeve-bearing and the tubular support, and a stop attached to thebeater-shaft to prevent it from moving longitudinally in thesleeve-bearing, substantially as set forth.

3. In a flour bolt, the combination of areel having a head provided.with a projecting tubular support, a beater -shaft within the tubularsupport, a sleeve-bearing surrounding the beater-shaft and mountedloosely in said tubular support, and a pinion, G, attached to thebeater-shaft and operating as a stop to prevent longitudinal'movement ofthe beater-shaft, and also to drive the spur-gear G', substantially asset forth.

4. In a flour-bolt, the combination of areel having a head provided witha projecting tubular support, a beater shaft within the tubular support,and a sleeve-bearing having a globe-shaped expanded portion and acylindrical part, E', projecting into the tubular support and toward thereel-head, substantially as set forth.

5. In a flour-bolt, the combination of a reel having a head providedwith a projecting tubular support, a beater-shaft arranged within thetubular shaft a sleeve-bearing having a cylindrical portion of lessdiameter than the I O opening in the tubular support and arrangedtherein, a lug, d, projecting from the sleevebearing, and a seat in theinner wall of the tubular support to receive the lug, substantially asset forth.

6. In a flour-bolt, the combination'of the reel having two heads, eachprovided with a projecting tubular support, a beater-shaft within thetubular supports, sleeve-bearings mounted loosely in the tubularsupports, a I IO beater-shaft within the sleeve-bearings, and stopsrigidly affixed to the shaft and engaging with the outer ends of thesleeve-bearings, substantially as set forth.

In testimony whereof I affix my signature in I I5 presence of twowitnesses.
